Key Parameters

Substitute Part Grouping Explanation

The 3362U-1-254LF qualifies as a direct substitute for the PVC6M254A01B00 based on the following matching parameters:

• Resistance value: 250 kOhms (identical)
• Power rating: 0.5W, 1/2W (identical)
• Tolerance: ±10% (identical)
• Temperature coefficient: ±100ppm/°C (identical)
• Number of turns: 1.0 Turn (identical)
• Adjustment type: Top Adjustment (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pins (identical)

The primary difference is the resistive material composition (ceramic versus cermet) and physical dimensions, which remain within acceptable mechanical compatibility for PC pin through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The 3362U-1-254LF is the qualified substitute for the PVC6M254A01B00. Selection of this substitute is supported by:

• Active product status, ensuring long-term availability and supply chain continuity
• ROHS3 compliance, meeting current environmental and regulatory requirements
• Identical electrical specifications across all critical parameters
• Same form factor and termination style for direct PCB compatibility
• Cermet resistive material provides enhanced stability compared to ceramic composition

The obsolete status of the PVC6M254A01B00 makes transition to the 3362U-1-254LF necessary for new production and ongoing support of existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 3362U-1-254LF be used as a direct replacement for the PVC6M254A01B00?

A: Yes. Both parts share identical electrical specifications (250 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1.0 turn, top adjustment) and the same PC pin through-hole termination. Physical dimensions are comparable within standard PCB layout tolerances.

Q: What is the difference between ceramic and cermet resistive materials in this application?

A: Both materials meet the specified tolerance and temperature coefficient requirements. Cermet composition in the 3362U-1-254LF provides improved long-term stability and environmental resistance compared to ceramic.

Q: Why is the PVC6M254A01B00 obsolete?

A: The PVC6M254A01B00 has been discontinued by the manufacturer. The 3362U-1-254LF represents the current active equivalent in the Bourns trimmer potentiometer product line.

Q: Are there packaging differences between these parts?

A: The PVC6M254A01B00 is supplied with standard packaging, while the 3362U-1-254LF is supplied in tube packaging. Both are suitable for through-hole assembly processes.

Q: Does the 3362U-1-254LF meet current compliance standards?

A: Yes. The 3362U-1-254LF is ROHS3 compliant and REACH affected, meeting current environmental regulations. The obsolete PVC6M254A01B00 does not meet these standards.
